Hmm- it would
be nice if they identified the manufacturer that has
notably higher failure rates, but I think I can make a guess (WD?)
Google's paper addresses this. One, because they're buying so many
drives, they think if everyone knows which is "best" then that will
increase demand and drive up the price for those drives. Two, they
don't want to help their competition. Three, they didn't want to get
sued by the losers.
An explanation of why they find printing the data inconvenient or
frightening does not negate the fact that it would be nice to have.
